Grounds and you may Outcomes of Monogamy
The human being lifetime record pattern (i.e., brief delivery times, apparently highest youngster endurance, and several years out-of juvenile dependency) means that mothers usually are about standing regarding support multiple dependents of various decades at the same time.
